    摘要： In connection with compression-coding of video signals on the basis of inter-frame correlation, a single reference table is used for variable length encoding of inter-frame motion vectors established on the basis of various motion vector value ranges and degrees of accuracy. A reference table is provided for variable length encoding motion vectors based on a particular value range and degree of accuracy. In order to use the same table for motion vectors based on a larger value range than that for which the table was designed, the value of a motion vector to be encoded is divided to form a quotient and a remainder. An addition bit code is formed on the basis of the remainder and is appended to a variable length code which corresponds in the reference table to the quotient so that a variable length code value is formed for the motion vector based on the larger range. As to motion vectors based on a finer degree of accuracy than was provided for in the reference table, the motion vector value is multiplied by an appropriate factor and the resulting product is used to obtain a corresponding variable length code value from the reference table. Decoding is performed using the same table and by means of decoding operations that are the inverse of the encoding operations.

    摘要翻译： 结合帧间相关的视频信号的压缩编码，单个参考表用于根据各种运动矢量值范围和精度确定的帧间运动矢量的可变长度编码。 基于特定值范围和准确度提供了可变长度编码运动矢量的参考表。 为了使用相对于基于与设计表相比较大的值范围的运动矢量的相同的表，将要编码的运动矢量的值被分割以形成商和余数。 基于剩余部分形成相加位码，并将其附加到在参考表中对应于商的可变长度码，以便基于较大范围为运动矢量形成可变长度码值。 对于基于比参考表中提供的精度更精确的运动矢量的运动矢量，将运动矢量值乘以适当的因子，并且使用得到的乘积从参考表中获得相应的可变长度代码值。 使用相同的表格和通过与编码操作相反的解码操作进行解码。

    摘要： Video signal transmitting system in which digital video signal are divided into groups of predetermined frames. Digital video signals of at least one frame are intraframe coded and then transmitted. Remaining digital video signals are interframe coded with reference to the intraframe coded digital video signals, and intraframe coded digital video signals of a subsequent group of frames and are then transmitted. A motion vector from a predetermined reference frame is detected. Video signals are interframe coded by the motion vector to transmit the video signals. A motion vector from a first frame which is a plurality of frames away from the reference frame is converted to a motion vector for a one frame interval between the reference frame and the first frame. The motion vector is optimized, and is then transmitted.
